Melanin absorbs harmful radiation, particularly ultraviolet (UV) light, by converting the energy from the radiation into harmless heat. Its complex molecular structure allows it to effectively dissipate this energy, thereby protecting skin cells from DNA damage that can lead to skin cancer and other harmful effects. By absorbing UV radiation, melanin acts as a natural sunscreen, reducing the risk of oxidative stress and inflammation in the skin. This protective mechanism is crucial for maintaining skin health in sun-exposed areas.
What else can I help you with?
How does the epidermis guard against harmful radiation?
Melanin is the dark pigmentation contained in skin. It is contained in melanocytes, which are the cells which produce melanin. The purpose of melanin is to filter out harmful radiation from the sun. Mostly it does not. The best way is to use a sunscreen with SPF of 30 or more.
What does the tyrosinase do for the body?
Tyrosinase is an enzyme that catalyzes the production of melanin, the pigment responsible for skin, hair, and eye color. It plays a crucial role in protecting the skin from UV radiation by producing melanin to help absorb and scatter harmful rays.
What melanin does?
Melanin shields the nucleus from damage by ultraviolet radiation. It keeps this radiation from damaging the skin and DNA. It also gives color to your skin, hair, and irises. Melanin is a pigment which gives characteristic color to skin. Its main role is to absorb harmful UV radiations and protect our skin cells from damage. It determines the color of your skin. Melanin colors hair, skin, eyes, feathers, etc.
What is melanin and what does it determine?

What are skin the adaptation that make it an effecient human shield?
Skin serves as a protective barrier against harmful microorganisms, UV radiation, and physical injury. It contains melanin to absorb UV radiation and prevent DNA damage, as well as immune cells to fight off infections. The epidermis continually sheds dead skin cells to prevent the buildup of pathogens.
How does the presence of more melanin affect skin pigmentation and protection from UV radiation?
The presence of more melanin in the skin leads to darker pigmentation, which provides better protection from harmful UV radiation by absorbing and scattering the rays.
Why does the skin tan in the sun?
It's a defence mechanism against the Sun's harmful UV radiation, using the pigment melanin.
What is the main function of melanin in the human body?
Melanin is a pigment that gives color to the skin, hair, and eyes. Its main function is to protect the skin from the harmful effects of UV radiation from the sun.
What pigment prevents the radiation from harming structures in the under layer of the skin?
Melanin is the pigment that protects structures in the under layer of the skin by absorbing and scattering harmful radiation from the sun, such as ultraviolet (UV) rays. Melanin helps to prevent damage to DNA in skin cells and reduces the risk of skin cancer and premature aging.
What is the mechanism of a suntan?
A suntan is the skin's way of trying to protect itself from the damaging effects of ultraviolet (UV) radiation. When exposed to UV radiation, the skin produces more melanin, a pigment that darkens the skin. This darker pigment helps to absorb and scatter the UV radiation before it can cause more damage to the skin cells.
What is melanin synthesis?
Melanin synthesis is the process by which cells in the skin produce melanin, a pigment responsible for the color of skin, hair, and eyes. This process is influenced by genetics, exposure to sunlight, and hormonal factors. Melanin plays a key role in protecting the skin from the harmful effects of UV radiation.
Why is skin black?
Skin color is determined by the amount of melanin, a pigment produced by cells called melanocytes in the skin. People with darker skin have more melanin, which helps protect against harmful UV radiation from the sun.
